 ### Fixes
 - Fix test related to preventing coercion of boolean values (True,False) to numeric values (0,1) in query results ([#58](https://github.com/dbt-labs/dbt-redshift/blob/1.0.latest/CHANGELOG.md))
+- Fix table creation statement ordering when including both the BACKUP parameter as well as the dist/sort keys ([#23](https://github.com/dbt-labs/dbt-redshift/issues/60))
